Time Delay Relays Dedicated - Delay-on-Make TDM / TDMH / TDML SERIES * Delay-on-Make Timer *8-pin models UL listed when used in combination with P1011-6 socket only. Description The TDM/TDMH/TDML Series is a delay-on-make timer that combines accurate digital circuitry with isolated, DPDT relay contacts in an industry standard 8-pin plug-in package. DIP switch adjustment allows precise selection of the time delay over the full time delay range. The TDM/TDMH/TDML Series is the product of choice for custom control panel and OEM designers. Operation (Delay-on-Make) Upon application of input voltage, the time delay begins. The 8-PIN output is de-energized before and during the time delay. At the end of the time delay, the output relay energizes and remains energized until input voltage is removed. Reset: Removing input voltage resets the time delay and output. Wiring Diagram Features & Benefits FEATURES BENEFITS Wide delay range User selectable via DIP switches for fine tuning to (0.1s to 2.8h) individual applications. Microcontroller based Repeat Accuracy + / - 0.1% Dip switch adjustment Provides first time setting accuracy of +/-2% Setting accuracy +/-2% Provides flexibility for use in most applications LED indication Provides visual indication of time delay status Relay contacts are isolated.
